That's a different link than the one I was thinking of, but I came here to post it all the same! Definitely encourage everyone to post in support of increased documentation and specific examples on why you'd use it.

which was your link?

I wonder why is much more expensive.

They would need to store and load the model, even if I imagine that they are using something similar to LoRA to finetune their models.

i would guess that the ideal price is also to raise the charge to make finetuning a last resort rather than a first resort; its probably much better cost- and research-wise if everybody just prompts the same model than silo off in their own minimodels.

Generating from a finetuned GPT 3.5 Turbo is 8x the cost of generating from the base model, so you really have to be in the “reduce prompt size by 90%” bucket they mention to get cost effectiveness out of it.

Early testers have reduced prompt size by up to 90% by fine-tuning instructions into the model itself, speeding up each API call and cutting costs.

I wonder if that 90% is precisely due to the calculation you made.

Just an older post about GPT-3.5 and fine tuning requests.

Could you elaborate? It may not be a replacement, but I can think of a few use cases where RAG could be avoided entirely by having the model be fine tuned on the right dataset.

There is a risk of (greater) hallucination if there aren't explicit sample inputs provided by RAG.

Finetuning teaches skills. RAG provides 'facts.'

I'm out of this particular loop. What does 'reduce prompt size' mean in this case? What is the advantage?
